Background: In states in the USA without in vitro fertilzation coverage (IVF) insurance coverage, more embryos are transferred per cycle leading to higher risks of multi-fetal pregnancies and adverse pregnancy outcomes.
Objective: To determine frequency and cost of selected adverse perinatal complications based on number of embryos transferred during IVF, and calculate incremental cost per IVF live birth.
Methods: Medical records of patients who conceived with IVF (n = 116) and delivered at >20 weeks gestational age between 2007 and 2011 were evaluated.
Preantral follicle development has become an increasingly recognized area of study in the last two decades. Factors that regulate the growth survival and differentiation of these small, yet complex structures have been identified. The field of fertility preservation and a need for increased numbers of mature oocytes for stem cell research revealed how little we knew of how follicles got from the primordial stage to the antral stage with a healthy and competent oocyte inside.

The present review focuses on the virology and complex immunology of this RNA virus in general and in relation to pregnancy.

Because recent data have suggested that epigenetic abnormalities such as abnormal placental DNA methylation may play a role in human pregnancy failure, we undertook experiments to test whether decidual and/or placental DNA methylation abnormalities are present in a mouse model of pregnancy failure. A large number of studies have shown that crosses between CBA/J female mice and DBA/2 males result in pregnancies with a high rate of failure/resorption, whereas other crosses with CBA/J females produce normal pregnancies.

This prospective time-motion analysis captured data on average time spent on 31 representative components of the IVF sequence as provided by clinical team members in seven categories. Audits of consumables and observations on personnel costs were made from total of 120 fertility patients undergoing initial or second IVF cycles (n=736) between 1 January 2002 and 31 December 2002 at a UK assisted fertility unit.

In this study, we characterized the effect of diabetic pregnancy on vascular growth of the maternal uterine vasculature and on the passive mechanical properties of the uterine resistance arteries. Diabetes was induced in pregnant rats by injection of streptozotocin and confirmed by development of hyperglycemia.
